Transverse waves have motion perpendicular to velocity, while longitudinal waves have motion parallel to velocity.

Explanation:

The correct option of all is that transverse waves have motion perpendicular to velocity while longitudinal waves have motion parallel to velocity.

A wave is a disturbance that transmits energy from one point to another. There several types of waves like sound, electromagnetic , ocean waves etc.

  • Waves can be classified as either longitudinal or transverse waves based on the direction through which they are propagated.
  • Longitudinal waves are waves propagated parallel to the source of velocity.
  • An example is sound waves and seismic p-waves.
  • They have series of rarefaction and compression along their path.
  • Transverse waves are propagated perpendicular to their source.
  • An example is electromagnetic waves in which electrical and magnetic fields vibrates perpendicularly.
